Application filed February 1, 1910, Serial No. 541,243. Renewed March19, 1917. Serial No. 155,943.

To all whom it may concern:

Be it known that I, MAX CYRUS OVERMAN, a citizen of the United States,and resident of the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements inVehicle-llheels, of which the following is a specification.

My present invention relates to improvements in vehicle wheels and moreparticularly tomeans for perfectly securing the tire to the wheel andpreventing it from creeping and at the same time permitting the removaland reattachment of the same or another tire in a highly convenient andexpeditious manner. The invention is applicable to all forms of wheelwhether resilicut or otherwise.

In the drawings, which show one of the particular forms which myinvention may take, Figure 1 is a perspective view of a wheel embodyingmy invention, Fig. 2 is a perspective view of one of the washersemployed in the construction, Fig. 3 is a perspective view of a portionof the rimand tire in my connecting devices, Fig. 4 is a transversesection partly in elevation through the rim and tlre and connecting devices, Fig. 5 is a perspective view of one of the clamping plates, andFig. 6 shows one of the wires useful in assembling.

Describing now the devices of the drawings and reserving it to theclaims to point out the novel features and to indicate the scope of theinvention, it being understood that said claims will be interpreted withdue and proper range of equivalents, P designates a tire shown attachedto the felly H of a vehicle wheel whose spokes are designated M. Thetire shown is in the form of an arch having inwardly directed baseportions. Ordinarily, these base portions will be circumferentiallycontinuous. Furthermore, each may have circumferential grooves o and win its opposite faces for purposes hereinafter described.

X is a metal rim having an inwardly directed flange Q and an outwardlydirected flange Y adapted to be secured to the folly H of the wheel inthe relation shown with the metal rim X at the tread of the felly H andwith the flange Q in contact with one side of said felly. This relationof metal rim and felly is maintained by any suitable means not shown, asfor example, by bolts passed through the parts and holding them rigidlytogether. As to the metal rim itself, the preferred construction is thatthe inwardly directed flange Q be braced to said rim X.

Z is a ring adapted to 'be bolted to the non-flange side of the main rimX and has an inwardly directed flange R contacting with the side of thefelly H and an outwardly directed flange F corresponding with thesimilar flange Y and being located at the side of the tire.

It will be noted from Figs. 1 and 3 that the ring Z is secured to therim X by a plurality of bolts projecting upwardly through the rim andthence through the ring Z which, for this purpose, is slotted (as bestshown at I in Fig. 3) not only through its portion Z, but also throughits inwardly directed flange R. The result is that when the nuts andwashers, next to be described. have been removed from these bolts, theentire ring can be removed laterally from the wheel. On the other hand,when the ring has been put back into position, it may be secured rigidlyin that position by dropping the washers A over the stems of the boltsand then applying the nuts C. This accomplishes the result because thewashers A are so wide that they cannot pass through the vertical portionof the slot l, and in addition are long enough between the bolt and theflange R of the ring to keep said flange in contact with the felly andconseouently to keep the entire ring rigidly held against lateraldisplacement.

The felly H and the metal rim X are perforated at intervals around thewheel with radially extending bolt-holes into which are received thestems of inwardly directed bolts K. These bolts support clamping platesL which, when the nuts J of the bolts are screwed up tight, serve toclamp the base portions of the tire against the rim. There will be aplurality of these clamping plates, each preferably more or less areshaped, as shown in Fig. 5, to conform with the curvature of the wheel.Preferably also each clamping plate will have inwardly directed edges Ireceivable into the circular grooves or recesses 'w in the outer side ofthe base'portions of the tire.

O designates circumferential beads proj ecting from the outer face ofthe rim X, one

or more on each side of the center tobe received into the correspondingcircumferential grooves 1. already described in the inner face of thebase portions of the tire.

Looking at the assembled tire in Fig. 4, it will thus be seen that itsattachment to the wheel is such that it can neither pull off radially orlaterally, nor can it creep. On the other hand, the devices are suchthat the tire is very easily removable and replaceable.

Thus, to remove the tire it is only neces sary to remove the nuts J andC and then to take off the ring Z and after that the tire.

On the other hand. to attach the tire, the first operation will be tosuspend the bolts K in their openings on the ends of wires, one of whichis shown in Fig. 6. For this purpose, it will be noted that the outerends of wires are provided with hooks receivable through eyes S in theends of the bolts. Further, it will be noted that the opposite ends ofthe wires are too large to pass through the bolt openings and thereforethe bolts are all held suspended ready to be drawn up into theirposition shown in Fig. 1 by pulling the wires inwardly toward the hub ofthe wheel.

The bolts having been suspended, the base portions of the tire areworked into the position shown in Fig. 4: between the clamping platesand the metal rim X. Thereupon, the bolts B for securing the ring Z areinserted into position. Next,the ring itself is put on and the washers Aand nuts C applied. Finally, the bolts K having been drawn up intoposition by the wires, the nuts J are screwed on, and all of the nutshaving been made properly snug, the attachment of the tire is complete.

The tire shown presents an unusually great depth of live rubber in acontinuous vertical line between tread and rim. This securescorrespondingly great supportin capacity, also resilience. On the otherhand, lateral displacement of the tire in rounding corners and so forthis prevented by the side support offered by the relatively deep flangesQopiea of this patent may be obtained for five cents F, the latterpreferably rounding out at their free edges 7.

What I claim is 1. In combination, a wheel rim, a ring telescoping overthe free edge of said rim having an inwardly directed flange and anoutwardly directed flange, the latter located at the side of the tire.bolt means extending radially relative to the wheel through theaforesaid rim and ring, theclatter being slotted together with itsinwardly directed flange to permit the stems of the bolts topass whenthe ring is adjusted to the rim, and washers for said bolts which arenon-passable through the slots and which engage the inwardly directedflange on the ring to hold it against lateral displacement.

Q. In combination, a wheel rim, a ring telescoping over the free edge ofsaid rim having an outwardly directed flange located at the side of thetire. bolt means extending radially relative to the wheel through theaforesaid rim and ring, the latter being slotted to permit the stems ofthe bolts to pass in adjusting the ring to the rim, washers for saidbolts, and projections on said ring engaging said washers to preventlateral displacement of the ring.

3. In combination, a. wheel rim, a ring telescoping over the free edgeof said rim having an outwardly directed flange located at the side ofthe tire, bolt means extending radially relative to the wheel throughthe aforesaid rim and ring, the latter being slotted to permit the stemsof the bolts to pass in adjusting the ring to the rim, washers for saidbolts, and means on the ring preventing its lateral displacement byengaging the periphery as distinguished from the face of the washers.
